There is no display on the
Polycom CX400 handset.
The cradle is not receiving power
or the handset battery is
discharged.
Refer to Power and Startup on page 3-2.
The display shows incorrect
information, even though the
handset appears healthy. The
display may show information for
another user. The display may
not show any user specific
information at all.
There may be a problem with
Microsoft Office Communicator
2007 or Microsoft Office
Communications Server 2007.
Contact your system administrator to
ensure your account is configured
properly and that your Microsoft Office
Communicator 2007 client software and
the Microsoft Office Communications
Server 2007 software are properly
installed and configured.
The handset may not be properly
paired, or your handset may be
paired with another user's cradle.
Do the following steps:
• Check that you have not accidentally
swapped handsets with another user,
and ensure that suspect handsets are
actually being used with their own
cradles.
• If necessary, re-pair your handset and
cradle. Refer to Pairing the Polycom
CX400 Handset and Cradle on page
1-5.
The display is flickering. Certain types of older fluorescent
lighting may cause the display to
appear to flicker.
Do one of the following steps:
• Move the Polycom CX400 cordless
phone away from the lights.
• Replace the lights.
The handset battery may be
weak.
Verify that the handset battery is charged.
For example, the screenshot below shows
a battery that needs charging.
